Adding multiple IP's to IPS Exceptions

Does anyone have a good solution for entering in multiple IP addresses? I need to add over one hundred IP's for a online learning site that we use, and really don't want to add them all individually. Shouldn't there be a wildcard, or *, or something to simplify this? This is an example of what I need to add.

- 72.249.13.0 - .63

I know that I can open up the whole subnet of 72.249.13.0 - .255, but that seems unwise to me.

Hoping I'm not the first Astaro user that's run across this issue before and I'm curious what others have done to resolve it.

Thanks!
